Natural Heritage Inventory
Tracking Wisconsin’s Rare Species, Natural Communities and Geological Features
Wisconsin's Natural Heritage Inventory (NHI) Program is part of an international network of inventory programs, and it is one part of the Bureau of Natural Heritage Conservation. We are responsible for assessing population and occurrence status of Wisconsin’s native plants and animals, natural communities and geological features, together referred to as “elements” of biodiversity. We track the locations and viability of rare species occurrences along with high-quality examples of natural communities and geological features throughout the state, these elements make up the “NHI Working List.”
